#15091: "Invalid proxy settings" and Pidgin does not reconnect (XMPP, vpnc)

Component:  unclassified     |   Version:  2.10.0    
 Keywords:  proxy reconnect  |  
-----------------------------+----------------------------------------------
 Ubuntu 11.10 (all updates applied). I have an XMPP (over SSL) chat account
 which I always keep open. When I go on VPN using vpnc, setting my GNOME
 network proxy (HTTP & HTTPS specified) in "manual" mode, after a couple
 minutes Pidgin disconnects with the message "Invalid proxy settings -
 Either the host name or port number specified for your given proxy type is
 invalid". (I am not sure what is "invalid" about my settings since they
 work for other applications such as Chromium.) Annoying but not a serious
 problem; I click Close.

 Later when I set the proxy back to "none" and close the VPN connection,
 the Buddy List window displays "<...name...> disconnected: Unable to
 establish SSL connection". Clicking Reconnect makes the message go away
 but does not actually reconnect. I have to go to the Account menu and
 reenable the account before Pidgin is back to normal. Pidgin ought to be
 reconnecting automatically once the network configuration is back to its
 previous state.


 Log excerpts when the connection is initially lost:
